Siftwren privacy policy

Last updated November 13, 2026. This policy covers the Android app Siftwren: Swipe Photo Cleaner (com.tinyfair.siftwren) published by Tinyfair on Google Play.

The short version

The app works on your device. We do not have accounts or servers, and we never receive your photos, videos or anything in them. Data leaves your device only for ads, purchases, crash reports and anonymous usage statistics (Google), and for a small settings file the app downloads from our website, as described below.

Data that stays on your phone

Photos and videos
Siftwren reads your photos and videos through Android's media permission, which you grant yourself (all photos or only the ones you select). They are checked on your device to find duplicates, similar and blurry photos. Nothing is uploaded, and the ad and statistics SDKs never receive your pictures, file names or anything found in them.
Sorting progress
Your swipe decisions, review bin, favorites, progress per month, picture fingerprints used to group similar photos, streak and statistics are kept in the app's private storage on your device.
Deleting and compressing
Photos are deleted only after you confirm in Android's own dialog. Compressed copies are saved to your gallery as new files.
Purchases
Handled by Google Play; we never see your payment details.

Settings file from tinyfair.my.id

When it starts, the app downloads a small settings file from https://tinyfair.my.id/config/siftwren.json (the minimum app version and how often ads may appear). The request sends no personal data and no identifier. Like any web request, our web host sees your IP address in its standard server logs; we do not use it to identify you or link it to anything else. Android Auto Backup may include the app's settings in your Google account backup if you have it turned on; your photos and videos are not part of it.

Ads (Google AdMob)

The free version shows ads from Google AdMob: a banner on the statistics and big video screens, an occasional full-screen ad after a deletion is finished (never while you swipe, never in your first session, at most a few a day), a full-screen ad when you come back to the app (not on first use), and a video ad only when you choose to watch one, for example for 24 hours of Pro. To show and measure ads, Google may collect your device's advertising ID, an approximate location from your IP address, information about ad interactions, and diagnostics. Your photos and videos are never passed to the ad SDK. In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent first, and you can change it later under Settings, Privacy choices. You can reset or delete your advertising ID in your Android settings. See how Google uses information from apps that use its services. Pro removes all ads.

Crash reports (Firebase Crashlytics)

If the app crashes or hits a serious error, it sends a crash report to Firebase Crashlytics, a Google service that helps us find and fix the bug. A report contains the error and where it happened in the code, the app version, the device model, the Android version, and a random installation ID that is not linked to you, your Google account or your advertising ID. It never contains your photos, videos or file names. Reports are kept for 90 days. See Firebase privacy and security.

Usage statistics (Google Analytics for Firebase)

To learn which features people use and where the app can be better, the app sends a few general usage events to Google Analytics for Firebase, such as that a month was sorted, a deletion finished and how much space it freed, an ad was shown, or the Pro offer was shown or Pro was bought. Events never contain your pictures, file names or album names. Firebase adds the app version, device model, Android version, country, a random app instance ID and, when ad consent allows it, your advertising ID. Collection follows your choice (Google Consent Mode). We do not use Google signals, we do not send a user ID, and we do not sell this data. In the European Economic Area, the United Kingdom and Switzerland, statistics are only collected if you allow it in the consent form (Settings, Privacy choices lets you change this). Data is kept for 14 months. See Firebase privacy and security.

Usage statistics (Google Analytics for Firebase)

To learn which features people use and where the app can be better, the app sends a few usage events to Google Analytics for Firebase: that the main screen opened, that a main task finished (for example "saved"), that the Pro offer was shown or Pro was bought, and that an ad was shown. Firebase adds the app version, device model, Android version, country, a random app instance ID and, when ad consent allows it, your advertising ID. Events never contain your photos, videos or file names, your name, email or anything you type. We do not use Google signals, we do not send a user ID, and we do not sell this data. In the European Economic Area, the United Kingdom and Switzerland, statistics are only collected if you allow it in the consent form (Settings, Privacy choices lets you change this). Statistics are never collected for users under 13. Data is kept for 14 months. See Firebase privacy and security.

Purchases (Google Play)

Pro is sold through Google Play Billing as a weekly, monthly, 3-month or yearly subscription (the yearly plan has a free trial for new subscribers) or a one-time lifetime purchase. Subscriptions renew automatically until you cancel them in Google Play. We do not see your payment details; Google Play tells the app only whether Pro is active.

Permissions

Photos and videos (READ_MEDIA_IMAGES, READ_MEDIA_VIDEO, and on Android 14 and later the option to allow only selected photos; storage read on Android 12 and earlier), because sorting and deleting your gallery is what the app does. No "all files" access. Notifications, only for the optional daily reminder you turn on; it is set again after the device restarts (start at boot). No camera, microphone, location or contacts permission. Google's ad and purchase libraries add the advertising ID, network state and billing permissions. Internet is used for ads, purchases, crash reports, usage statistics and the settings file described above, never for your photos or videos.

Children

The app is not directed at children under 13 and we do not knowingly collect information from them.

Your choices and deleting data

Siftwren has no account and keeps no data on our side. Your sorting progress and statistics can be reset in the app. To delete everything Siftwren stores, uninstall the app or clear its storage in Android settings (Apps, Siftwren, Storage); your photos stay in your gallery unless you deleted them. For ad and statistics data, use Settings, Privacy choices in the app or your Android advertising ID settings. Questions: support@tinyfair.my.id.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions: support@tinyfair.my.id.
